I have to replace my default brake discs for my m240i , i also saw that for my car i can also use the performance disc ( 09.c394.13)

Do this part fits my bmw , and is it also better then the default disc ?

The image below shows the Brembo parts catalog page for your 2017 M240i xDrive: https://www.bremboparts.com/europe/e...-i/000120248-1.

It shows that the 09.C394.13 disc does fit your car. However, that disc requires the M Performance Brake Kit: https://www.bimmerworld.com/BMW-M-Pe...t-F22-F3X.html. That kit has a front caliper of a different size to accommodate the 370mm front disc versus the standard 340mm disc.

thanks,
yes i already discovered this.. well i narrowed my search and found two other vendors for new discs.

Zimmermann formule F or the Textar Pro +

seems people are happy with this brake discs

today i did order the ;

Stoptech drilled Disc
DS2500 Pads
Stoptech StainlesS brake line kit
Castrol SRF fluid

I also think the drilled disc are looking better then the ventilated disc, it takes 2-3 weeks until installing this ( before my pure turbo 800 upgrade )

it should brake a little bit better i hope...

Are you replacing your OEM 2-Piece Rotors with the same?
.
.
Is 2-Piece lighter? or just a cheaper way to manufacture vs 1-piece?
.
.
I installed the OEM alternative Pilenga Rotors but is there really a difference??

[kriszty]

i,m replacing all 4 rotos with the stoptech drilled.
pads with the ds2500 , also the brake lines and new oil

replacing the lines and the oil and the pads is the biggest step i think.
the drilled disc are more cosmtic but should help also a small bit i hope

[kriszty]

anybody driving with 1-piece stoptech disc ?? want to know if this is better then the OEM bmw disc

[kriszty]

decided to go with the OEM BW Disc 34106797602 part drimpled and grooved
